COM Signature

From vsshell80.idl:


HRESULT IVsObjectList2::GetSourceContext(
   [in] ULONG Index, 
   [out] const WCHAR **pszFileName, 
   [out] ULONG *pulLineNum

This method is used to display the source file and line number in the find symbol results window. You can return E_NOTIMPL if you don't want to display this information.

The text buffer is created by the IVsObjectList2 object, and the buffer must persist for the life of the IVsObjectList2 object.

If you are implementing this interface in managed code and you need to have the string disposed by the caller, implement the IVsCoTaskMemFreeMyStrings interface on the IVsObjectList2 interface.
